Introduction

This species was described from a series of small squid (maximum size was 19 mm ML) obtained from the stomach of the lancetfish Alepisaurus ferox. In spite of its small size, the species was recognized as being distinct by the presence of a relatively broad mantle and small visceral photophore.

This page is a Tree of Life Leaf Page.

Each ToL leaf page provides a synopsis of the characteristics of a group of organisms representing a leaf at the tip of the Tree of Life. The major distinction between a leaf and a branch of the Tree of Life is that a leaf cannot generally be further subdivided into subgroups representing distinct genetic lineages.

For a more detailed explanation of the different ToL page types, have a look at the Structure of the Tree of Life page.
